I noticed that all three topics in this open forum were bumped this morning by an anonymous guest. So I looked into that, and it makes sense that an anonymous guest can do this. So going forward, knock yourself out anonymous guests. But you can only bump a topic once every 10 days. (That's a setting I can control, but I believe it applies to all forums - I can't just change it for this open forum.)

And note that if you bump all the topics, that's the same as not bumping at all!
